[TG11] Axiom - display of wind data in True or Apparent
On chart page. Is wind icon True or Apparent?

On dash board Navigation Page. Wind icon is labeled True. Can it be set to Apparent? On Sailing page it is set to apparent.

RE: Axiom - display of wind data in True or Apparent
Hello carlmk,

The Wind Vector overlaid on chart is True Wind Direction (true wind angle corrected for current vessel heading.)
In the Dashboard app's Navigation page shows both True and Apparent wind with arrows labelled T and A. You can display either True, Apparent or Ground wind as a digital value in a data-box in the Dashboard app also. Apparent is just what's measured, True is adjusted to remove the effect of boat speed-through-water, whilst Ground wind is adjusted with GPS data and vessel heading in order to give the wind direction over the ground.

Regards,
Tom
